Abstract Piezocone penetration test(CPTU) has advantages in directly providing the most original soil parameters and reflecting in detail the nonlinear variation of deformation with depth. The relationships between the parameters of piezocone profiles and the parameters of p-y curve were established and the p-y curve method using the CPTU data for determining the horizontal bearing capacity of single pile was proposed. The method was verified by comparison with the in-situ pile data from Jingjiang，Suqian and Kunshan sites. Results indicate that the p-y curve method based on CPTU can accurately reflect soil resistance development characteristics，which is a highly efficient and rapid method for determining the horizontal bearing capacity of pile foundation.

Key words： pile foundation piezocone penetration test(CPTU) p-y curve horizontal bearing capacity in-situ test
